What should be added to $$\dfrac{2}{3} + \dfrac{3}{5}$$ to get $$\dfrac{-2}{15}$$?

Asked by Sakshi | 1 year ago |  57

##### Solution :-

Let us consider a number as x to be added to $$\dfrac{2}{3} + \dfrac{3}{5}$$ to get $$\dfrac{-2}{15}$$

$$x + ( \dfrac{2}{3} + \dfrac{3}{5}) = \dfrac{-2}{15}$$

By taking LCM of 3 and 5 which is 15 we get,

(15x + 2×5 + 3×3)15 = $$\dfrac{-2}{15}$$

15x + 10 + 9 = -2

15x = -2-19

x = $$\dfrac{-21}{15}$$

Further we can divide by 3 we get,

$$\dfrac{-21}{15}= \dfrac{-7}{5}$$

the required number is $$\dfrac{-7}{5}$$
